Unable to edit button label – Possible bug

I am not sure if it may be a bug on the latest update that was released today but I was unable to edit the title of the button. I managed to use a bit of jquery to force the label change. I have placed it below incase somebody else might have a similar issue:

<script type="text/javascript">
jQuery(document).ready(function(){
setTimeout(function(){
jQuery(".loadMoreBtn-label").text("Load More");
}, 1000)
});
</script>
